Wow. Screwed again! That's about like every time
I walk in to Skycraft in Orlando, FL and walk back
to their drawers of TTL. I always check the drawers
labeled 7441, 74141, 74142....and I always see the same
old dust in each of them, but no ics.
However, checking the 4500 drawer, I found it slam full!!
Bought 5 of them, and have yet to fire up a 4500, but
am planning to when I have some time. 4500 is a one-bit
16-instruction processor. And, here's the best part
about it: It can run at a clock speed from DC to 1 mHz.
I like the DC part. (can you say push-button?)
